7. Horizontal movement of the P.U.arm for 7" = 17.5 cm discs [45rpm]
As already known, we must play for gramo. phonographs with a diameter of 7 "the diameter slide in

normal way already described. T he control disc rotates at a constant speed and now touches the small
steering hook , which rotates around its axis.The steel wire spring (FIG 9 1 13 ) attached to the end of this

this starts to rotate, which causes

determined by the distance

) The roller turns

small handlebar from the inside to the
outside and leaves at a given moment the small steering hook, which shoots back under the influence of
the torsion spring (FIG 9 1 17 ) and bumps against the diameter shifter, but now also the large steering
hook is no longer swiveled and the PU is
just above the beginning of a 7 "plate, because the distance of the P.U. is greater than that of 25 cm
(10") plates and the times used are almost the same, the speed for both
